    摘要： A video decoder, a video decoding method, a video encoder and a video encoding method are disclosed. A video decoder for decoding a video bitstream for an image block includes a motion vector resolution reducer and a motion compensator. The motion vector resolution reducer is for receiving decoded high resolution motion vectors included in the video bitstream and for reducing an accuracy of the high resolution motion vectors to correspond to a low resolution. The motion compensator, in signal communication with the motion vector resolution reducer, is for forming a motion compensated high resolution prediction using the reduced accuracy motion vectors. The video encoder for encoding scalable video comprises a motion compensator for forming a motion compensated full resolution prediction and combining the motion compensated full resolution prediction from an image block to form a prediction residual. The prediction residual is downsampled to form a low resolution downsampled prediction residual and then coded.

    摘要： A method and apparatus for staggercasting includes encoding a set of signals representing content such that each encoded signal, alone or in combination with other encoded signals, is capable of being decoded to produce a corresponding decoded signal. Each decoded signal has a reproduced quality which different from the reproduced quality of all the other decoded signals. A composite signal is generated including the set of encoded signals. The encoded signal corresponding to a lowest quality decoded signal is undelayed. The other encoded signals are delayed by different amounts such that the higher the quality of the corresponding decoded signal, the longer the delay period. The set of encoded signals is extracted from the composite signal, and errors in the set of extracted encoded signals detected. A subset of available extracted encoded signals which are not erroneous is produced. A content representative signal at the highest quality possible is decoded from the subset of available extracted encoded signals.

    摘要： A method and apparatus for staggercasting a plurality of content representative signals includes encoding a first and a corresponding second signal representing each of the plurality of content representative signals. A composite signal is generated comprising the plurality of first and second encoded signals. In the composite signal, each respective second encoded signal is delayed with respect to the corresponding first encoded signal. The first and second encoded signal representing a selected one of the content representative signals is extracted to reproduce the selected content representative signal. The extracted first encoded signal is decoded if an error is detected in the extracted second encoded signal, otherwise the extracted second encoded signal is decoded. When a different content representative signal is newly selected, the first extracted encoded signal is decoded until the delayed second extracted encoded signal is available.
